What does Freedom Calcs do?

Freedom Calcs is a free collection of financial independence and retirement calculators. It includes tools for Coast FIRE, Barista FIRE, Fat FIRE, Lean FIRE, and calculating your FIRE number.

The Coast FIRE calculator estimates how much you need invested today for your portfolio to grow toward a future retirement target without additional contributions. Enter your age, invested assets, retirement spending, and monthly contributions, then adjust return, inflation, and withdrawal assumptions to explore different scenarios. Results update automatically, with a growth chart, projection data, and contribution comparisons shown in today's dollars.

The site explains its formulas, sources, and model limitations so you can understand how each estimate is calculated. It works on desktop and mobile without an account, and financial inputs are processed in your browser. The calculators are educational tools and do not provide personalized financial advice.
